Earlier this week The Brothers Grimsby stars and real-life spouses headed over to Kris Jenner's house to give Kim Kardashian, Kanye West and Kourtney Kardashian an early screening of their new R-rated comedy. Momager Kris' boyfriend Corey Gamble was also there for the star-studded get together, and so was Courteney Cox with her daughter Coco Arquette!

The Brothers Grimsby was a hit with the Kardashian-West gang, but we were all left wondering how the heck this movie night came together. Well, E! News' Erin Lim caught up with the stars Thursday at the premiere of The Brothers Grimsby, and Isla explained just how organically one of her friends set the whole thing up.

"Well, I had never met them [the Kardashian-Jenner-West bunch] before, and my husband asked Courteney Cox—since our movie is so quintessentially English—do you know an average American family that can see it and tell us what it's like?" she said. "Smash cut to the Kardashians in the living room!"

"They really laughed and they really loved the movie, so fingers crossed that everybody else likes it too," added Isla."Because, of all [Sacha's] comic characters, I've gotta say that this one's my favorite."
